This was a small earthquake. Shaking like this is often felt indoors nearby and very rarely causes damage.

At this magnitude and depth, people at rest would likely notice it out to about 37 km (23 mi) from the epicentre. In Long Beach, 25 km away, the estimate is intensity II (weak). Estimated from magnitude, depth and distance with the intensity equation USGS Did You Feel It? uses; felt reports, where there are any, are the measurement.

Likely felt in: Avalon 24 km, intensity II · Long Beach 25 km, intensity II · Rancho Palos Verdes 26 km, intensity II · Seal Beach 26 km, intensity II · Huntington Beach 27 km, intensity II · Signal Hill 30 km, intensity II · Newport Beach 31 km, intensity II · Palos Verdes Estates 31 km, intensity II. Estimated for each town centre; each link is that town's own record.

How big was it?

This earthquake released about 990 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 4.0 would have released about 32 times as much.

  2. Mineral, Virginia 2011 M 5.8 15,000× the energy of this one
  3. Magna, Utah 2020 M 5.7 11,000× the energy of this one
  4. This earthquake M 3.0 about 990 lb of TNT

Energy from the Gutenberg–Richter relation (log10E = 1.5M + 4.8), rounded to two figures; bar length is magnitude, which is already a logarithm of energy. Magnitudes of past earthquakes from the USGS catalogue.

For this area

The largest earthquake within 50 km since 2016 was M 4.3 on 2021-09-18 — about 80 times the energy of this one.

Before 2016, the USGS record lists 5 earthquakes of M5 or more within 50 km:

  1. 6.4 The 1933 Long Beach, California Earthquake · 25 km ENE of this epicentre
  2. 5.3 7km W of Newport Beach, CA · 25 km ENE of this epicentre
  3. 5.1 The 1941 Torrance-Gardena, California Earthquakes (Second Event) · 27 km N of this epicentre
  4. 5.0 2km ENE of Westminster, CA · 35 km NE of this epicentre
  5. 5.0 2 km NE of Carson, California · 34 km N of this epicentre

Since 2016: the QuakeIndex catalogue (US, M1.5+), built from the USGS FDSN event service. Before 2016: USGS ComCat, M5+ from 1900. Distances are between epicentres. This is the record, not a forecast.
